Measuring the Height

To measure the exact height of a Dasani 20 oz bottle, you need a ruler or measuring tape. Place the bottle upright on a flat surface and measure from the bottom of the bottle to the top of the cap. Most standard 20 oz Dasani bottles measure approximately 8.5 inches in height. However, there can be minor variations:

  • Older or specialty bottles may be slightly shorter or taller
  • Bottles sold in different countries use metric measurements
  • Bottles with unusual shapes may not stand exactly 8.5 inches tall

On average though, the 20 oz Dasani bottles commonly sold in the US will measure between 8 and 9 inches in height when standing upright. Expect a measurement around 8.5 inches for a standard bottle.

Factors Affecting Height

Several factors can account for small variations in the height of Dasani 20 oz bottles:

  • Manufacturing tolerances – During factory production, bottle height dimensions may vary slightly between production runs and molding equipment used.
  • Plastic thickness – Thicker, more rigid plastic may make the bottle a bit taller, while thinner plastic could result in a shorter bottle.
  • Cap style – Shorter caps like sports caps reduce the total height slightly compared to regular screw caps.
  • Shape – Unusual bottle shapes and designs impact the overall height.
  • Location sold – International bottles use metric measurements so a 500ml bottle may be a slightly different height than a 20 oz (591ml) US bottle.

But even with these small variations, most standard 20 oz Dasani bottles you’ll find in stores measure right around 8.5 inches in height. The height is designed for convenient holding and storage in cup holders.

Dasani occasionally releases special edition bottles with unique colors, designs, or graphics. These special bottles commemorate events like the Olympics or feature seasonable designs. But the shape and height generally remain consistent with a standard Dasani bottle.

Why a 8.5 Inch Height?

Dasani carefully engineers their bottle heights to be convenient and comfortable for consumers. Here are some of the reasons why the 8.5 inch height is ideal for a 20 oz bottle:

  • Fits easily in most cup holders in cars, holders, backpacks, etc.
  • Height provides capacity for approximately 20 fluid ounces of water.
  • Easy to grip with one hand while drinking.
  • Stands upright nicely in a refrigerator door.
  • Standard size to fit with bottling production lines.
  • Conforms to typical PET plastic bottle specifications.
  • Similar heights used across brands for consumer familiarity.

Through consumer testing and factoring in manufacturing considerations, Dasani settled on around 8.5 inches as an optimal height. This provides the right balance of capacity, portability, and drinking convenience.

History of the 20 oz Bottle

The 20 ounce plastic bottle has become a standard over the last few decades:

  • 1970s – PET plastic bottles introduced, starting to replace glass.
  • 1980s – Plastic bottling technology improves, various sizes including 20 oz emerge.
  • 1990s – Single serve 20 oz bottles popular in convenience stores, vending machines.
  • 2000s – Wide adoption of 20 oz size across bottled water, sodas and other beverages.
  • 2010s – 20 oz remains one of the most ubiquitous plastic bottle sizes.

With the improvements in plastic molding and bottling equipment, companies like Dasani helped make the 20 oz PET bottle a familiar sight. Its popularity endures decades later thanks to its versatility across many beverage types and markets.

Use Cases

The 20 oz Dasani bottle serves multiple consumer usage cases:

  • Convenience – Single serve bottle for grabbing on the go from the store, vending machine, water cooler, etc.
  • Portability – Fits easily in bags, coolers, cup holders for hydration away from home.
  • Storage – Slim profile takes up less space in refrigerators or pantries.
  • Travel – Compact shape and size for taking in cars, planes, hotels, etc.

The bottle’s 8.5 inch height and 20 oz capacity make it ideal for people on the move. It’s no wonder the size remains popular years after its introduction.

Alternatives to Plastic Bottles

While plastic water bottles like Dasani are popular, there are concerns over sustainability and plastic waste. Some alternatives to conventional plastic bottles include:

  • Reusable water bottles made of metal, glass, etc.
  • Cartons made of renewable materials like paperboard
  • Compostable bottles made of PLA plastic from plants
  • Cans and pouches with reduced plastic
  • Refillable water station options

However most alternatives don’t quite match the light weight, convenience, and cost of conventional PET bottles. So plastic still dominates single-serve bottled water. Hopefully innovations will provide more sustainable options in the future.
